' in Bleaching, Cleansing, and Sizing Compounds and Processes for Making the Same, of which the following is a specification.

My invention relates to a bleaching, cleansing and sizing compound, and the process for making the same. n

Heretofore the chlorid of lime and sulfuric acid used to bleach vegetable fibers have injuriously affected the same, burning the fibers, rendering them harsh, brittle and impairil'ig their efficiency and elasticity. The process heretofore'used requiresa number a stand for about twenty-four hours, during of acetic aci of-st eps such as boiling in soda, treatment in chlorld of lune, sulfurlc acld, and a number of wash ngs.

With the present invention vegetable fibers and the like can be bleached very quickly in one bath, cheaply and without anyinjury to the fibers.

To produce the new compound, I take about six parts of chlorid of lime and mix with about one part of salsoda or carbonate of soda, sufficient water is added to the mixture to form a paste, which is allowed to which time a hypochlorit e oi sodaw,andian insoluble carbonateoTliineis formed. Then there is added to the product formed, about two parts of (potash soap and about one part The soap and pyroligneous acid prevent the burning of the fibers and the carbonate of lime combines with the soap and produces a size. may be omitted.

To use the compound is mixed with about six parts of water at about 70 de i2 0 be treated.

-Having described my invention I cla m: 1. The process of making a bleachlng,

about six parts of chlorid of lime with one part of salsoda, adding water to the mixture to, form a paste, allowing the mixture to ducing a hypochlorite of soda and an insoluble carbonate of lime, and adding two parts of potash soap.

2. The process of making. a bleaching,

about six parts of chlorid of lime with one to form a paste, allowing the mixture to stand about twenty-four hours, thereby producing a hypochlorite of soda and an insoluble carbonate of lime, and adding two parts of potash soap and one part of acetic acid.

3. A bleaching, cleansing and sizing com pound comprising a hypochloritc of soda, carbonate of lime and soap.

4. A bleaching," cleansing and sizin compound comprising a hypochlorite'o soda, carbonate of lime, soap and acetic acid.
